Always, with any movie that I do, I have a book of ideas that I've heard, or seen, or whatever, and I always try to incorporate it in the film.

I wanted to make a movie about the arbitrary nature of love.

Their every instinct - and I have to say this is without exception - is to iron out the bumps, and It's always the bumps that are the most interesting stuff.

Always, with any movie that I do, I have a book of ideas that I've heard, or seen, or whatever, and I always try to incorporate it in the film.

What I think is interesting is that the more you do, you have to invent a book of rules of what you can do and what you can't do. And the very real danger is that if your book of rules becomes a book of cliches.

It's the sort of subject that always interests me: jealousy and the language of suspicion and guilt. I think it interests people.

The challenge, really, on any new film is to try to avoid that and achieve a few moments that aren't cliche.
